Title: Method for purifying dye
Inventor: KOBAYASHI MASATSUNE
IPC: C09B67/54
Filed: 1983-07-07
Abstract: PURPOSE:To remove inorg. salts in an aq. dye soln. and to lower the concn. of Ca ion, by purifying an aq. dye soln. by both ultrafiltration and a contacting treatment with a specified chelating resin. CONSTITUTION:An aq. soln. of a water-soluble dye, particularly a dye as a raw material of ink for ink jet recording is treated by an ultrafiltration method to reduce the concn. of inorg. salts in the dye to 1% or below. The aq. soln. is then brought into contact with an aminoalkylsulfone type chelating resin [e.g.- a macroporous resin composed of a styrene/divinylbenzene copolymer matrix and having a chelate-forming group of formula I (wherein X is H, Na)] to lower the cncn. of Ca ion to a level suitable for use in the ink for ink jet recording, i.e. to reduce the concn. of Ca ion to 1ppm or below by the reaction represented by the reaction formula II (wherein ''-'' represents a hight-molecular matrix moiety). By using both treatments, the dye can be purified in the form of an aq. soln. without using any org. solvents to obtain a highly purified raw material.

Title: Method of coating liquid resist
Inventor: MASUDA TSUGUNORI
IPC: H05K3/06
Filed: 1986-05-28
Abstract: PURPOSE:To prevent accumulation of a liquid resist bank by changing a relative positional relationship between a screen and a printed wiring substrate in a horizontal direction at each time when the printed wiring substrate is supplied on a lower side of the screen of a screen printing machine. CONSTITUTION:The relative positional relationship between the screen 29 and the printed wiring substrate P in the horizontal direction is changed at each time when the printed wiring substrate P is supplied to the bottom side of the screen 29, namely, the positions of a through hole of the printed wiring substrate P are different from each other at the times of the first resist coating and the 2nd resist coating. Therefore, the resist bank 32a stuck on the bottom surface corresponding to the through hole at the 1st resist coating disappears by coating it on the surface of the printed wiring substrate Pa at the 2nd resist coating. Although the resist bank is formed on the bottom surface of the screen corresponding to the newly formed through hole Ha, said resist bank also disappears at the following resist coating. Thus, the partial accumulation of the resist bank in the screen corresponding to the through hole of the printed wiring substrate is prevented.

Title: Sampling circuit
Inventor: SATO HIDETOSHI
IPC: H04L7/00
Filed: 1994-06-06
Abstract: PURPOSE:To provide the reception data of improved quality causing wrong data at the time of binary conversion by a mall circuit scale. CONSTITUTION:The changed point of data 20 is detected and phase detection output 30 is obtained. Sampling clocks 40 are respectively frequency divided to 1/4 cycle and 1/2 cycle of one bit of the data 20 in the sampling circuits 7 and 8. The frequency divided output 70 and 80 is alternatively transmitted corresponding to the phase detection output 30 and the data 20 are sampled corresponding to the frequency divided output. When a state for which the contents of the bit of reception signals are the same continues, sampling is performed at the time at the approximate center of the width of one bit. When the contents of the bit change, the sampling is performed at the time earlier than the time at the approximate center of the width of one bit. Thus, since a timing is changed and controlled corresponding to the presence/absence of the change of bit contents, a correct sampling result is obtained even when a pulse width per bit fluctuates due to the mixing of noise and electric field intensity change.

Title: Portable telephone set
Inventor: YOSHIMURA KENICHI
IPC: H04B1/10
Filed: 1995-05-23
Abstract: PURPOSE: To ensure a best sound output by controlling an electronic volume so as to decrease a level of a reception sound output gradually when a received electric field strength reaches a prescribed level or below so as to reduce noise. CONSTITUTION: An RF section 1 detects a received electric field strength RSSI during speech to provide an output to a CPU 2. The CPU 2 controls output quantity of a received sound based on the RSSI. In this case, when the RSSI reaches a level lower than a prescribed level, the CPU 2 controls an audio processing section 3 so as to gradually decrease an output level of an electronic volume. When the level of the RSSI is not recovered, the electronic volume is finally muted completely. Furthermore, since a frequency band at which noise is easily generated in an output of the electronic volume is changed due to the level of the RSSI, the CPU 2 controls a frequency control circuit 4 so as to limit an output of the circuit 4 at a frequency band where noise is easily generated based on the level of the RSSI.

Title: Diagnosis method of secondary air supplying device
Inventor: ITOU TOKIJI
IPC: F01N3/22
Filed: 1992-05-15
Abstract: PURPOSE:To realize accurate diagnosis of the operation of a secondary air supplying device even when the output signal of an air fuel ratio sensor becomes temporarily lean, and preliminarily prevent erroneous diagnosis. CONSTITUTION:The air fuel ratio of the mixture to an engine 1 is detected by an oxygen sensor 18. When the operational condition of the engine 1 is the preset one, the fuel injection from fuel injection valves 8A-8D is adjusted so that the air fuel ratio may be the theoretical value. When the operational condition is not the preset one, a secondary air supplying device 23 is activated and the secondary air is supplied to an exhaust passage 3. The return time by the oxygen sensor 18 during the secondary air supply is measured by the count action of the timer, and when the return time exceeds the specified value, a judgement is made that the secondary air supplying device 23 is normal. In such diagnostic operation, when the air fuel ratio by the oxygen sensor 18 becomes rich, the count action is stopped and the current timer value is maintained, and the count action is continued after elapse of the specified period of time.
